One aspect of the deal is Japan’s pledge to purchase all of the excess corn from the U.S. that Trump says China originally agreed to purchase but has failed to do so.

"We have excess corn in various parts of our country with our farmers because China did not do what they said they were going to do. And Prime Minister @AbeShinzo, on behalf of Japan, they're going to be buying all of that corn." — President @realDonaldTrumppic.twitter.com/cqRTDeKZLR

U.S. Trade Representative Robert Lighthizer identified three key areas that make up the agreement — agriculture, industrial tariffs and digital trade.
